I've on occasion seen people misinterpreting the check mark as:
- The answer is correct/perfect
- The answer is approved
So when the answer doesn't meet those expectations, the asker may not accept (even if it was very helpful and the issue was resolved), or a passer-by may get vocal, downvote, etc.
When I joined the site I had to learn from the help center that it only means it's the most helpful to the asker, and nothing else.
Where I actively contribute, I have more than 50% accept rate, so just to be clear, this is not coming from "Your design is bad and I'm not getting enough Internet points". Rather, making the meaning more accessible, especially in light of the possible upcoming change to how accepted answers are sorted.
For example, the one on the right shows a user selection.
Given that, should the 'accept' icon be updated (not either design specifically)? Or not?
The above are not the proposed designs.
I'm asking: Should it be changed?; the design is up to SE. They can design and show us examples to choose from, for example.
